"He's put three pretty good years together for us since I've been here," Capitals coach Barry Trotz said. "I just think he's gotten better and better every year because it's becoming normal for him to have a high-quality standard. Those great goaltenders or great players in this league, they do it the right way all the time and Braden's one of those guys, and that's why he's had great success."

Holtby, 27, won the Vezina, voted on by the League's general managers, for the first time last season. Sergei Bobrovsky of the Columbus Blue Jackets and Carey Price of the Montreal Canadiens are the other Vezina finalists this season.
The winner will be announced at the 2017 NHL Awards at T-Mobile Arena in Las Vegas on June 21 (7:30 p.m. ET; NBCSN, SN).
"He deserves it again," Capitals center Jay Beagle said. "He's an unbelievable goaltender. He works his hardest every day, so it's good to see."
After tying Martin Brodeur's NHL record with 48 wins last season, Holtby led the League with nine shutouts this season, and his 42 wins tied for first with Cam Talbot of the Edmonton Oilers. Holtby joined Brodeur and Evgeni Nabokov as the only goaltenders in League history with three consecutive 40-win seasons.
Holtby also ranked second in the NHL with a 2.07 goals-against average and fourth with a .925 save percentage among goalies who made at least 25 appearances. Holtby and Bobrovsky were the only two goaltenders to rank in the top five in wins, shutouts, GAA and save percentage.
